How many spectral bands does Sentinel-2 have?
13 spectral bands
SENTINEL-2 carries an optical instrument payload that samples 13 spectral bands: four bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution. The orbital swath width is 290 km.
What is NDMI in remote sensing?
The NDMI (Normalized Difference Moisture Index) describes the crop’s water stress level and is calculated as the ratio between the difference and the sum of the refracted radiations in the near infrared and SWIR, that is as (NIR-SWIR)/(NIR+SWIR).
What is Mndwi index?
“The Modified Normalized Difference Water Index (MNDWI) uses green and SWIR bands for the enhancement of open water features. It also diminishes built-up area features that are often correlated with open water in other indices.
How many bands are there in Sentinel 2?
Sentinel 2 has a total of 13 bands. Each band is 10, 20 or 60 meters in pixel size. This includes red, green, blue, near infrared and short infrared bands. Sentinel Band Combinations We use band combinations to better
How big is the resolution of Sentinel 2?
We have the Sentinel 2 images since 2015, and with a resolution of 10 meters you can do an infinite number of things that will impress us. Previously we saw how to download the Sentinel images, but now we present a summary of the most common combinations of the Sentinel 2 spectral bands in channels such as red, green, blue (RGB).
Are there going to be more Sentinel 2 satellites?
Two additional satellites (Sentinel 2C and 2D) are planned to launch in 2020 and 2021. This will make a total of four Sentinel-2 satellites. Overall, these 2 additional satellites will cut the revisit time in half. Sentinel-2 carries the Multispectral Imager (MSI).
Which is band to use for remote sensing?
Check out the Sentinel-2 specification SENTINEL-2 Radiometric Resolutions to find: So the band combination becomes (B08A – B11) / (B08A + B11). Band 12 range (2070 ~ 2340 nm) is far off for your requirement.
